APPARATUS FOR DELIVERING SHEETS.

SPECIFICATION forming part of Letters Patent No. 504,874, datedSeptember 122, 1893.

Application filed May 12, 1892. Serial No. 432,808. (No model.)

To all whom it may concern.-

Be it known that I, SAMUEL G. GOss, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a certain new and Improved Apparatus for Delivering Sheets, ofwhich thefollowing isaspecification,reference being had to theaccompanying drawings, in which- Figures 1, 2 and 3 are diagrammaticviews, showing the position of the different parts of the apparatus andshowing the sheets in their different positions. Figs. 4,5 and 6 aresimilar views, showing the apparatus modified for delivering singlesheets withasingle fold.

My invention relates to apparatus for delivering the sheets of anewspaper or other fabric, and is in some respects similar to myapplication, Serial No. 432,807, filed of even date herewith for sheetdelivery apparatus.

The object of my invention is to provide new and improved means forassociating the sheets. I accomplish this object as hereinafterspecified and as illustrated in the drawings.

That which I regard as new will be pointed out in the claims.

In the draWings,-1 and 2 indicate folding and cutting cylinders, whichare substantially similar to those described in my applicationhereinbefore referred to; the folding cylinder 1 carrying a foldingblade 3 which is adapted to force the sheet into the bite of foldingrollers 4 and 5 carried by the cylinder 2. The folding rollers 4. and 5may be operated by any suitable mechanism, preferably that shown in myapplication above referred to, to

cause them to grip the sheet to carry it to tapes 6 and then release it.

7 and 8 indicate cutting blades carried by the cylinder 2, which bladesregister with recesses 9 and 10 respectfully carried by the cylinder 1.By this construction, the web will be severed into sheets each of alength equal to half the circumference of the folding cylinders 1 and 2.

11 indicates a guide adapted to strip the folded sheets from thecylinder 2.

12 indicates tapes which are mounted on rollers 13, 14. and 15, whichrollers are so located as to carry the web in a proper direction to feedit to the folding cylinders 1 and 2, as shown.

16 indicates tapes mounted upon rollers 17 and 18, the object of whichwill be hereinafter set forth.

19indicates guide rollers,which are mounted upon a suitable shaftparallel with the shaft upon which the cylinder 1 ismounted, asindicated by the diagram.

20 indicates guides which extend from the upper portion of the cylinder1 to the upper portion of the rollers 19, and are adapted to conduct thesheets from the cylinderl to the rollers 19, as best shown in Fig. 3.Thetapes 16 serve to carry the sheets over the guides 20. The ends ofthe guides 20 which are adjacent to the cylinder 1, preferably fit intogrooves in said cylinder and serve to strip the sheets from thecylinder. The guides 20 are mounted upon a cross bar 21 or othersuitable supporting device.

22 indicates guides which are in general similar to the guides 20, andserve to guide the web as it is carried along by the tapes 12 from therollers 19 to thelower portion of the cylinder 1. The upper ends of theguides 22 are curved, as shown, and fit between the rollers 19. They notonly serve to guide the web to the lower portion of the cylinder 1, butalso serve to direct the associated sheets in the proper direction. Theguides 22 are mounted upon supporting bars 23 or other suitable devices.

24. indicates shoes, which are mounted upon a shaft 25 and serve todirect the sheets around the rollers 19, as shown.

26 indicates the web to be delivered.

To deliver two sheets with asingle fold, the web 26 is carried by thetapes 12 to the under side of the cylinder 1, where it isimpaled by pins27 carried by said cylinder, and is then carried around ninety degreesto the position shown at 28 in Fig. 2, the cylinders 1 and 2 rotating inthe direction indicated by the arrows in Fig. 2. At this point thecutting blade 7 will lie in the recess 9 of the cylinder 1. As thecylinder 1 continues its rotation, the end of the web will be carriedaround to the upper side of the cylinder 1, and will there be strippedfrom the cylinder by the guides 20, and when it reaches the positionshown in Fig. 3 the cutting blade 8 will sever the sheet from the web,as shown in Fig. 3. At the next half revolution of the cylinder 1, thesheet thus severed will be carried to the position shown at 29 in Fig. 2to be partly associated with the web 26. At the next half revolution theweb will be severed in line with the forward edge of the superposedsheet, as shown in Fig. 3, and at the next quarter revolution the weband the sheet superposed upon it will be in the position shown in Fig.1, and will be folded by the folding blade 3, as shown at 30in Fig. 1.At theneXt quarter revolution the associated sheet and web will be inthe position shown at 31 in Fig. 2, and the web will be severed at therear edge of the superposed sheet, thereby leaving two sheets with asingle fold. In starting the mechanism it will be observed that thesecond sheet severed from the web will be folded and delivered byitself, but all subsequent sheets will be associated as above described.

I have shown two rollers 32 and 33 on the cylinder 2 opposite therollers 4i and 5, but they are not used when associating two sheets.

To adapt my improved delivery apparatus for delivering single sheetswith asingle fold, I provide on the cylinder 1 a second folding blade34., which is adapted to register with the rollers 32 and 33. By thisarrangement ence of the second folding blade will not permit any of thesheets to pass back to the rollers 19, but will fold them as shown inFigs. 4, 5 and 6'.

The apparatus shown in Figs. 1, 2 and 3 is intended for use inassociating two sheets and giving them a single fold, as abovedescribed, but by providing different numbers of cutting blades theapparatus may be so arranged as to associate any desired number ofsheets before they are folded.

That which I claim as my invention, and desire to secure by LettersPatent, is

1. The combination of a pair of cylinders 1 having means for severingoneor more sheets 1 from a continuous web, mechanism for trans- 5 ferringthe severed sheet or sheets back to and superposin'g the same upon saidweb, and folding devices for folding the web and the sheet or sheetssuperposed thereupon, substantially as describe 2. The combination witha pair of cylinders having Web severing and folding devices, of guiderollers, suitable upper guides located between the upper portions of theguide rollers and the adjacent cylinder, suitable lower guides locatedbetween the lower portions of the guide rollers and the said adjacentcylinder, tapes for carrying a web along the said lower guides to thefolding cylinders, means for carrying a severed sheet from the cylindersalong the upper guides to the guide rollers, and devices fortransferring the severed sheet or sheets to and upon the web as it movestoward the cylinders, substantially as described.

3. The combination with a pair of cylinders having web severing andfolding devices, of

guide rollers 19, suitable guides located between the guide'rollers andthe adjacent-cylinder, tapes for carrying a web to the lower portion ofsaid adjacent cylinder, means for carrying a severed sheet from thecyli-ndersto 3 the guide rollers, and devices for transferring thesevered sheet or sheets around the guide rollers to and upon the web asit moves toward the cylinders, substantially as described. each sheetwill be folded singly, as the presa folding blade 3, a cylinder 2 havingfolding frollers 4i and 5 and cutting blades 7 and 8, 1 carrying tapes1-2 for carrying the web to the scylinders, guide rollers 19 cooperatingwith 4:. The combination of a cylinder 1 having said tapes, suitableguides 20 and 22 located between the guide rollers and the adjacentcylinder, tapes 16 for carryinga sheet or sheetsi from the cylinders tothe guide rollers, and devices for directing the severed sheet or sheetsunder the guide rollers to and upon the webasit moves toward thecylinders, substantially as described.
